The main aim of the present study was to map of Urmia Lake water surface diminishing rates over a long-term period, and demonstrating the most recent surface of emerged salty alluvial plains. For this purpose, Landsat TM, ETM+ and OLI imageries, observing from 1984 to 2015, were progressively processed to generate most of the thematic models in tempo-spatial context. All multi-date satellite da...

1. To prepare various thematic layers such as drainage density, lineament density, slope, lithology, geomorphology and landuse/land cover using SOI topographical maps, remote sensing data and GIS. 2. To prioritize the weightages of individual themes and feature score depending upon their suitability to hold groundwater. 3. To prepare the integrated final groundwater potential map (GPM) using th...

The objective of this research was to determine the best model and compare performances in terms of producing landuse maps from six supervised classification algorithms. As a result, different algorithms such as the minimum distance ofmean (MDM), Mahalanobis distance (MD), maximum likelihood (ML), artificial neural network (ANN), spectral anglemapper (SAM), and support vector machine (SVM) were...

     Reduction of water resources limits the ability of farmers for food production and subsistence. Nowadays the quick growth of population has been the most important factor in the decline of renewable water. In many parts of Iran, including region of interest, the major factor in water resources decline was land use change, that may  cause to ecological destruction and disruption. Sustainabl...

Emotions are often felt in the body, and somatosensory feedback has been proposed to trigger conscious emotional experiences. Here we reveal maps of bodily sensations associated with different emotions using a unique topographical self-report method. In five experiments, participants (n = 701) were shown two silhouettes of bodies alongside emotional words, stories, movies, or facial expressions...

The use of cartographic representations in 3D views accumulates the advantages of technological advances, but faces a lack of cartographic knowledge needed to build these representations. Consequences include misconceptions in map design that can inhibit or even impair the understanding of the features represented and their spatial relations. A common task in 3D map-use is virtual navigation su...

PURPOSE To assess the repeatability of corneal wavefront aberrations derived from Pentacam (Oculus) corneal topography. SETTING Flinders Eye Centre, Flinders Medical Centre, Bedford Park, South Australia, Australia. METHODS Forty-five normal participants and 10 participants with keratoconus were tested. Intraobserver and interobserver repeatability was determined using 4 observers within an...

A large-scale virtual reality town was used to test the topographical and episodic memory of patients with unilateral temporal lobe damage. Seventeen right and 13 left temporal lobectomy patients were compared with 16 healthy matched control subjects. After they had explored the town, subjects' topographical memory was tested by requiring them to navigate to specific locations in the town. The ...
